Simulation efficiency testing equipment for medicament used in oil well casing

The invention discloses simulation efficiency testing equipment for a medicament used in an oil well casing. The equipment comprises a liquid storage barrel, a middle barrel support is fixed to the side, close to the center, of the inner bottom face of the liquid storage barrel, a test barrel support is fixed to the other side, close to the center, of the inner bottom face of the liquid storage barrel, a middle barrel is installed at the top of the middle barrel support, and a test barrel is installed at the top of the test barrel support. In the present invention, a simple method and equipment are adopted; the detection problem of underground chemicals is basically solved; before the medicament is put into production and use; the analogue simulation test is realized; adoption of this technology, a small amount (about one thousandth of the actual measurement of an oil well) of medicament can be used; through simulation testing, a conclusion whether the reagent is effective or not is obtained, the effect of th
